Hi She says she asked the bank and they said they couldn't give her any more information. Seems odd to me - like they were fobbing her off as couldn't be bothered. She's 86 and pretty compus mentis but not very financially aware.

It isn't cold weather as she actually got more in July than this month. The bank just actually can't trace what it is so we're none the wiser.That said it is a credit not a debit so she isn't too worried!

We have also had CNI payments credited to both a joint account with LloydsTSB and my personal account with NatWest.Amounts of £93.58 and £232.16 and even £435.99.Neither Bank appears to be able to give details and my IFA is at a loss to understand it too.

The Centre for Protection of National Infrastructure seems to be all about 'threats to National Security' not Bank Statements. Curiouser and curiouser
